TENONING SPECIFICATION formingpart of Letters Patent No. 584,018, datedJune 8, 1897.

Application filed May 28, 1892.

Serial No.434,697. (No model.)

To all whom it 722-107 concern;

Be it known that I, ISAIAH SIcorTE, a citizen of the United States,residing at Cohoes, county of Albany, and State of New York, haveinvented certain new and useful Improvements in Tenoning-Machines, ofwhich the following is a specification.

M y invention relates to such improvements; and it consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference maybe had to the accompanying drawings, and the letters ofreference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure l of the drawings is a side elevation of my improvedtouching-machine. Fig. 2 is a vertical section taken on the broken line2 2 in Fig. 3. Fig. 3 is a top plan view of the machine as shown in Fig.l, partly in section, taken on the broken line 3 3 in Fig. 1.

The main frame of the machine comprises the uprights A A and theconnecting side bars A A one on each side of the frame. The side bars Asupport the bearings for the drive-shaft A upon one end of which isfixed the drive-pulley A and upon the other end the pulleys A A The sidebars A support the bearings for the cutter-shaft A provided with a fixedpulley A", connected by belt A with pulley A. The cutter-shaft supportsthe cutters for forming the tenons, which cutters consist of the twooutside saws B B for forming the ends of the slats, the toothed wheelsor planers B for forming the tenons, and the middle saw B for cuttingone slat from another by sawing the tenoned portions apart, forming acomplete tenon on one end of each of two slats.

The slats are fed to the cutters by hand in the form of a long strip ofthe uniform crosssectional form desired for the slat, and the cutterscut away portions of the slat to form the tenons.

I have indicated by the dotted lines a in Fig. 3 the form and positionof the slat-strip and aslat a just after the latter has been out fromthe former by the saw B c represents the The removtenons formed by thecutters.

able stop or gage B determines the length of the slat. The stop ispivoted upon the stud A projecting from the main frame.

I-leretofore the slat-strip has been forced through a central aperturein a gear or gears provided with yielding seats adapted to press againstthe slat with suflicient force to firmly clamp and hold the same whilethe cutter formed the tenons. In such a form of construction the forceof a strong man was necessary to push the slat-strip between theyielding seats, which were necessarily very strong to hold the slats.The operation was slow and laborious.

The object of my invention is to provide a more convenient andeasily-operated clamp for holding the slat-strip; and the inventioncomprises a split or sectional gear 0 O, having a central aperture 0 forthe slats. The two sections are each provided with gear-teeth adapted tomesh with a driving-pinion B fixed upon the shaft B. Power is transmitted to this shaft from pulley A through belt B pulley B shaft B andgear-wheels B and B the gear B being fixed upon shaft 13*. I prefer tomake use of a pair of such sectional gears, one on each of the oppositesides of the cutters, as shown in Fig. The sectional gears are eachprovided with a comparatively large journal G which journals are rotaryin bearings in the sectional boxes D D. The periphery of eachgear-journal is provided with an annular groove adapted to receive theinner portion of the sectional boxes, as shown in Fig. 3.

The box-section D is pivoted upon the gearshaft B and is pivoted to thesection D at D On the side of the sectional gear opposite the connectionD the two box-sections are loosely connected by the screw-bolt D whichpasses loosely through an aperture in the ear D and is screwed into anaperture in the ear D threaded to receive it. The box-section D is alsoprovided with an arm D, which is connectedwith treadle F by the link F.The treadle is pivoted at F upon the main frame and is connected by link13 with one end of a lever F, the other end of the lever being pivotedto the rod F lntermediately of its ends the lever F is pivoted to theshort arm of lever F, pivoted at F The long arm of this lever isprovided with a weight F adjustable longitudinally thereon. Secured tothe upper part of the main frame is a stop S for limiting the upwardmovement of the lever-arm D secured to or forming a part of theboxsectiou D, also a stop or stops S (shown in Fig. 2) for limiting thedownward movement of the lever D The gear-section O is also providedwith a stop S adapted to engage with the trip S bolted to the main frameat S when the sectional gear and bearing-box are open in a position tosupport the slat-stri p loosely, as shown in Fig. 1.

The operation of the machine is as follows: The slat-strip is insertedthrough the central aperture C until the inserted end strikes the stop13, and the treadle is pressed down until the lever D is moved from theposition shown in Fig. 1 to that shown in Fig. 2 and strikes the stop S,which limits the downward movement. \Vhen the several parts occupy theposition shown in Fig. 1, the weight F holds the arm D against the stopS and exerts an upward pressure upon the treadle through link F and uponthe bearing-box section D through the treadle-link F. The upwardpressure of section D is a power applied at connection D to separate thebox-sections, the stop S serving as a fulcrum for the lever formed bythe arm D and box-section D. As soon as a downward movement iscommunicated to the treadle the box-section D swings downwardly on theshaft B and applies power to the connection D to close the box-sections,the upper end of the rod F then serving as the fulcrum for the leverformed by arm D and box-section D. As soon as the fulcrum for such leveris changed from the stop S to red F the force of the weight is exertedto close the boxsections, which causes the gearsections to tightly clampthe inclosed slatstrip and securely hold the same while acted upon bythe cutters. As soon as the box and gear sections close the twoboxsections become as one lever fulcrumed upon the shaft I5, with thepower applied at the link connection with arm D. When the arm D strikesthe stop S, the box and gear sections have carried the slat-strip farenough for the cutters to form the tenon and for the middle cutter orsaw B to cut through the tenon and separate a completed slat from thestrip, the relative positions of the slat and cutters being shown inFig. 2, the exposed end of the slat being indicated by shade lines andthe portion behind the cutters by dotted lines.

The sectional gear is prevented from rotating when the sectionalbearing-boxes are in the position shown in Fig. 1 by means of the stop Sin engagement with trip S but the downwardly-swingin g movement of theboxsections causes the stop to slip past the trip, which releases thegear and permits it to be rotated in its bearings by the pinion untilthe tenon is formed and cut off. The treadle is then released, whereuponthe weight raises the treadle and other parts to the position shown inFig. 1, in which position the stop 5* engages with the'trip to stop andopen the sectional gear ready to receive the slat-strip and allow it tomove freely through its central aperture. \Vhen the rotary movement ofthcsectional gear is thus arrested, the belt B slips upon one of itssupporting-pulleys, and the rotary movement of the cutters continues.\Vhen desired, the gear-sections may each be provided with an adjustableslat-seat consist ing of a clamping-block II, movable in a radialslideway H in the gear-section and provided with a seat H in its faceadapted to receive one edge of theslat. The blocks are movable radiallyof the sectional gear and can be secured in different positions by theadjusting-screws II to accommodate the size or the central aperture C tovarying widths or slats.

The sectional gears can be easily inserted in and removed from the boxesby removing the bolt D and opening the sections.

By giving the slat aperture and seats the desired form my improvedsectional gear and sectional bearing-box are well adapted for use in allkinds of tenoning-machines having 1i revoluble or rotary cutter.

By the term slat I include any strip adapted to receive a rounded tenon.

lVhat I claim as new, and desire to secure by Letters Patent, is-' 1. Ina tenoning-machine, the combination with arotary cutter; of a rotarysectional gear having a central slataperture; means for opening andclosing the gear-sections; and means for varying the positions of thecutterbearings and gear-bearings, relatively to each other,substantially as described.

2. In a tenoning-machine, the combination with a rotary cutter of asectional gear having a central slat-aperture; a sectional boxcontaining the bearings for the gear; means for opening and closing thebox-sections for clamping the gear-sections upon the slat; and means forvarying the position relatively to each other of the cutter-bearings andgearbearings, substantially as described.

3. In a tenoning-machine, having a rotary cutter, a sectional gearhaving a central slataperture and an adjustable slat-seat in eacnsection of the gear, substantially as described.

4. In a tenoning-machine, the combination with a rotary cutter; of thesectional gear, (I. G, having a central slat-aperture; a sectionalbearing-box for the gear; a pivot connection. I3, between one section ofthe box and a fixed support; a pivot connection, D between the twobox-sections; and means substantially as shown and described foroscillating the sec tions upon their pivots.

In testimony whereof I have hereunto set my hand this 16th day of May,1892.
